Re: [Cfrg] Adoption of draft-agl-cfrgcurve-00 as a RG document

support adoption

These nits can be fixed whenever:

0) In s9, Watson/Tanja reminded me that we got this wrong in our draft (fixed in the editor’s working copy but not published):

old:
	e.g., as mask(s_t) = 1 - s_t
new:
	e.g., as mask(s_t) = 0 - s_t

1) In s9.1 (from a comment Rich Barnes made on our draft):

old:
	where 9 is the number 9
new:
	where 9 is the number 9, represented as a 32-byte
	integer in the little-endian representation described
	in Section 8.

2) In s9 & s9.1: (also from Richard):

There are a couple of magic values that appear, a24 in Section 4 and 9 in Section 5.  For a24, it would be helpful just to say "(see [Curve25519])" to reinforce that this document isn't making it up.  For 9, it would be helpful to note that this fixed value is simply the chosen base point for Curve25519 (in the language of traditional ECDH).

3) In s9.1 (also from Richard):

r/leftmost/most significant
r/rightmost/least significant

4) Needs a security considerations and an iana considerations section.
